Hard water is the through-line of Texas plumbing. San Antonio classifies as very hard and Dallas as hard, while Austin's lime-softened supply and Houston's blend both average moderately hard, so water heaters, fixtures, and valves across the state carry scale years before they fail outright. Freezes are occasional here, but the rare cold snap can be consequential.

Plumber licensing in Texas
The Texas State Board of Plumbing Examiners issues the state's plumbing licenses and registrations: Tradesman Plumber-Limited, Journeyman, Master Plumber, and Plumbing Inspector, plus registrations for apprentices, drain cleaners, and residential utilities installers. Journeymen, tradesmen and apprentices work under the supervision of a Responsible Master Plumber, any company offering plumbing must secure the services of one, and drain cleaners must be registered with the board.
- Authority. Texas State Board of Plumbing Examiners (TSBPE)
- License structure. Tradesman Plumber-Limited / Journeyman Plumber / Master Plumber / Plumbing Inspector, plus registrations (Plumber's Apprentice, Drain Cleaner-Restricted, Drain Cleaner, Residential Utilities Installer) and endorsements (e.g. Medical Gas Piping Installation)
- Worth knowing. A Journeyman installs, changes, repairs, services or renovates plumbing under the supervision of a Responsible Master Plumber, any company offering plumbing must secure the services of one, and drain cleaners and apprentices must be registered with the board.

What Texas conditions mean for plumbing
Utility figures put San Antonio around 300 mg/L (17.5 gpg), very hard, with Dallas near 138 mg/L (8 gpg), while Austin's lime-softened supply averages 93 mg/L (5.4 gpg) and Houston's main system a moderately hard 110 mg/L (6.4 gpg). Expect scale on heating elements and aerators across most of the state. Texas's mild freeze class means winters mostly pass quietly, yet an occasional hard freeze makes pipe insulation worth taking seriously.
